Talking to the Broadcasters on Twitter: Networked Gatekeeping in Twitter Conversations with Journalists

Drawing upon the theory of networked gatekeeping, this study describes how citizens engage in Twitter conversations with journalists and illustrates the power dynamic between traditional gatekeepers (journalists) and the gated (news audience). The power dynamic is discussed along four attributes of the gated—political power, information production ability, relationship with gatekeepers, and information alternatives. Results show that citizens interacted with gatekeepers by sharing information/opinion, social chats, and self-serving promotion of individual opinions and agendas. Politically active citizens interacted more often with journalists who share similar ideology. The citizens have varying degrees of political power, reflected by their different levels of involvement and influence in political discourse online. The implications for gatekeeping are also addressed.

Visceral and somatic hypersensitivity,autonomic cardiovascular dysfunction and low-grade inflammation in a subset of irritable bowel syndrome patients

The pathophysiology of irritable bowel syndrome (IBS) is complex and not fully understood, so the aim of this study was to evaluate whether visceral and somatic hypersensitivity, autonomic cardiovascular dysfunction, and low-grade inflammation of the gut wall are associated with diarrhea-predominant IBS (D-IBS). Sixty-two patients with D-IBS and 20 control subjects participated in the study. Using the ascending method of limits (AML) protocol, we demonstrated that D-IBS patients had significantly lower sensory thresholds compared with healthy controls (P<0.001). Using diverse methods, especially the ischemic sensitivity test, for the first time in China, we confirmed that D-IBS patients have somatic hypersensitivity. They had a significantly higher systolic blood pressure and heart rate after a cold stimulus, indicative of autonomic cardiovascular dysfunction. Compared with the control group, D-IBS patients had a significantly higher level of calprotectin (P<0.001). We also found significant correlations between visceral and somatic hypersensitivity, visceral hypersensitivity and autonomic cardiovascular dysfunction, and somatic hypersensitivity and autonomic cardiovascular dysfunction. Our findings may provide valuable suggestions for the treatment of D-IBS.

我国遗产景区门票价格涨价热的冷思考
